unmet dependencies:
Hello Everyone,
I am trying to update and install memcache on my zurmo VM. I can run apt-get update and it works fine then i try install-security-updates and ui get the following erorr.
+ SEC_UPDATES=FORCE + /usr/lib/inithooks/firstboot.d/95secupdates Reading package lists... Reading package lists... Building dependency tree... Reading state information... Reading package lists... Building dependency tree... Reading state information... E: You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: openssh-server : Depends: openssh-client (= 1:6.0p1-4) but 1:6.0p1-4+deb7u2 is installed Unmet dependencies. Try using -f.
I tried the apt-get -f install but get the same error. How can I fix this issue ??
Thanks
Bruce

TBH I'm not sure why apt won't just auto install it...
Reply 1That's weird
Reply 2I just checked a TurnKey v13.0 server (FWIW it was Moodle, but it shouldn't really matter) and both openssh-server and openssh-client are at version 1:6.0p1-4+deb7u2!
What do you get from the following?:
apt-cache policy openssh-server
Hope you don't mind I edited your post to make it a little easier on the eye! :)
Something is seriously messed up...
Reply 3And TBH I'm starting to run out of ideas. Is this a new (or newish) install or has it been around a while? Where abouts is it running? Is it on bare metal? A VM on a local machine? A VPS in the cloud?
Your screenshot is a bit hard to read so I'm not totally sure whether it is likely to be corruption, but perhaps try is to clean the apt cache and try again (in case the deb is corrupt).
apt-get clean && apt-get update && apt-get install -f
And/or
apt-get clean && apt-get update && apt-get install openssh-client openshh-server
Or if that doesn't work, then try manually installing OpenSSH client
dpkg -i /var/apt/cache/openssh-client*.deb
And repeat for OpenSSH server. Then keep your fingers crossed and hope that it works this time. Otherwise personally I'd be concerned about what else might be broken on your server and why... File corruption? Hardware on it's way out? Malicious attack? Misconfiguration caused by someone who doesn't know what they're doing mucking with your server? I don't mean to alarm you and TBH I have no idea. I'm only throwing ideas around, but if you haven't been fiddling with it and this has just occurred on it's own, I would be a little concerned and would probably be making sure that you have a recent backup (that you have tested) and perhaps even try deploying it on a fresh TKL machine (even if just a local VM) and see if that has the same issues.
Ok I did a bit of googling...
Reply 4From my research it seem likely that your issue is caused by the debconf package becoming corrupt. This leads me to 2 things:
Firstly, (assuming my research was right) you should be able to fix it by downloading and reinstalling debconf. Then fix your other packages... So try this:
wget http://ftp.us.debian.org/debian/pool/main/d/debconf/debconf_1.5.49_all.deb dpkg -i debconf_1.5.49_all.deb
Then try this again:
apt-get install -f
The second thing though, is why this happened in the first place... Personally I'd make sure that you have regular backups enabled (both for this VM and for the host's storage) and I'd encourage you to store a set of backups on some external storage (either a removable storage medium or another computer - i.e. not the host PC's HDD).
Great news! :)
Reply 5I'm so glad to hear that we got you going again! :)
Seeing as you have backups sorted, I'd probably do a disk check on the host system just in case there is some minor corruption on the HDD.
IMO apt should just take care of it (and update OpenSSH server if it needs to). But obviously it's not for some reason...
FWIW did you try fixing it with the following? That will often work...
I guess if that doesn't do it you could also try just manually update OpenSSH...
FYI the deb7u2 packages come from the main repo (not security - the deb7u1 package comes from security) so at some point you must have manually updated one of them... Not that that explains why it's not working now...
